T0 at whom it may concern.-

7 Be it known that I, JoNAs NORTHROP, a citizen of the United States,and a resident of Hopedale, county of Worcester, State of Massachusetts,have invented an Improvement in Hopper-Actuziting Mechanism forAutomatic Looms, of which the following description, in connection withthe-accompanying drawings, is a specification, like numerals on matictype, wherein the running filling is re-,

plenished from time to time by insertion of a fresh supply of fillinginto the shuttle.

United States atent to Northrop,. No. 529,940, shows a com of thisgeneral type, and laterpatents show various devices for advancing thehopper step by step to bring. into position to be transferred one afteranother of a plurality of filling-carriers or bobbins held as a reservesupply in the hopper.

In In present invention I have provided means or effecting the advanceof the hopper after each operation of the transferrer, the latter actingto transfer the filling-carriers from the hopper to the shuttle in sucha manner that the motion imparted to the hop-' per will be withoutsudden shock or jar, and I have also provided novel means forlimiting-the advance of the hopper to a predetermined distance.

In order that the hopper may not turn backward when the advancingmechanism is being set preparatory to the next advance, a detent isprovided. I i

When the attendant wishes to fill the hopper, it is sometimes necessaryor convenient to move the hopper freely in either direction, and hereinI have provided means whereby by manual movement of a single member ofthe controlling mechanism the hopper is entirely freed from suchmechanisms and can be moved in either direction by the attendant and thefilling-carriers placed therein as required. i I have illustrated myinvention in connection with a rotatable hopper of the Northrop type,such as shown in the patent hereinbefore referred to, and in order tocontrol the said hopper Ihave provided feed, detent,

rotatable with the hopper, the stop-pawl be-' ing automaticallyretractedby or through the setting movement of the feed-pawl, and

y manual retraction of one of said pawls,-

isengaged from the ratchet to free the hop er.

b preferably the feed-pawl, all of the pawls are These and other novelfeatures of my mand stop pawls to cooperate with a ratchet vention willbe fully described in the sub:

joined specification and particularly pointed out in the followingclaims.

Figure 1 is a transverse sectional view of the hopper of an automaticfilling replenishing loom of the Northrop type, taken across the axis ofrotation of the connected disks comprising the hopper and with oneembodi thereto, the parts being shown in normal position inreadiness forthe next filling-carrier to be, transferred when called for. Fig.2 is asimilar view, a portion of the hopper-disk being omitted asunnecessary,but showing the parts in the position desired at the instant that thetransferrer has completed its operative movement to insert a fi rier inthe shuttle, the feed-pawl having been set in readiness for the nextadvance of the hopper and the stop-pawl being shown as retracted topermit the initiation of such ad vance movement. Fig. 3 is a viewsimilar to Fig. 2, but showing the hopper as freed from ling-can thecontrol of its operating mechanism. Fig.

4 isa' side elevation of the transferrerdetached. Fig. 5 shows side andrear edge views of the feed-pawl. Fig. 6 shows side and top plan viewsof the stop-pawl; and Fig. 7 is a detached view, in side elevation, ofthe detent-pawl.

Inasmuch as the filling replenishing mechanism, broadly speaking, andthe means for I actuating the transferrer are not of my invention, thesame being well known to those skilled in the art, it will be suflicientto state that the hopper in practice comprises two connected disks orplates, the inner one, as 1, being herein shown rotatably mounted on adisk or stud 2, fixed to the hopper-stand 3, mounted on the breast-beam4 of the loom.

The filling carriers or bobbins 5 aresuitably held by their butts andtips by and between the two disks of the'hopper in a cirou larlyarranged series, as shown inv Fig. 1, and

7 O ment of my novel hopper mechanism applied by intermittent advance orstep-by-step movement of the hopper said filling-carriers are broughtone by one into transferring position adjacent a stop 6 to be engaged bythe rocking transferrer 7, and thereby transferred from the hopper tothe running shuttle all in well-known manner.

The transferrer 7 has its hub 8 mounted to rock on a horizontal stud 9,and it isretracted or lifted to normal position by a spring (not shown)and positively depressed or rocked on its operative stroke or movementby wellknown mechanism on the beat up of the lay.

I have herein shown a circular ratchet 10, secured to and to rotate withthe hopper, and in actual practice the ratchet is secured to or formedon the outer face of the disk 1, its

v teeth corresponding to the number of holding devices for thefilling-carriers.

The transferrer in my present invention is slightly different in certaindetails of construction, and, as best shown in Fig. 4, the saidtransferrer is provided with an upturned and enlarged extension 11 cutaway at its lower portion and offset laterally, as at 12, the parts 11and 12 being in different vertical planes, the offset portion 12 havinga lateral pin or stud 13 thereon, and adjacent the ont end of theextension a shelf 14 is provided having an upturned projection 15, theshelf forming a spring-seat and the projection serving to position the sring upon the seat.

The feed-pawl by whic 1 the advance movement of the filling-carrier iseflected is shown separately in Fig. 5, and consists of a casting havinga main body portion 16, provided at its rearward corner with aslightly-hooked finger 17, and at the outer corner the body is upturned,as at 18, and provided with a broad lateral tooth 19 to cooperate withthe ratchet 10. Oppositely projecting from the extension 18 is afinger-piece 20 for a purpose to be described, and viewing Fig. 5 itwill be seen that the finger 17 is slightly offset from the body portionof the pawl.

A depending foot 21 is provided with an elongated slot 22, and in frontof the slot is located an overhanging shoulder 23, having a dependingtip 24, which enters the upper end of and retains in position a coiledactuating-spring 25, (see Figs. 1, 2, and 3,) this spring beinginterposed between the shoulder 23 and the seat 14 on the transferrerhereinbefore referred to.

The pin or stud 13 on the transferrerloosely enters the slot 22 at thelower portion of the feed-pawl, and, observing Figs. 1, 2, and 3, itwill be seen that while the cooperation of the slot'and pin constitutesa positive connection at times between the transferrer and the feedpawlit is a lost-motion connection, permitting not only a rocking movementof the feedawl with relation to the transferrer, buta so a bodilylongitudinal movement of the pawl for a purpose to be explained.

The slot extension 21 bears against the face of the offset 12 of thetransferrer, and the main or body portion of the pawl bears against theopposed face of the enlargement 11, the two parts 11 and 13 being offsetfrom each other sufficiently to permit the easy insertion and movementof the feed-pawl between them.

The transferrer is firmly mounted on its fulcrum-stud (as is well knownto those familiar with this type of loom) and has practically no lateralmovement and the width of the pawl-tooth 19 is such that its inner endis close to the outer face of the hopper-disk 1. Thus the feed-pawlcannot become displaced laterally 011 the transferrer, and its11])-ft1](l.- down movement is limited by the slot-andpin connection.The actuating-spring 25 is of sufficient strength to advance the hoppera predetermined distance after the feed-pawl has been set, as will bedescribed, such setting compressing the spring, as shown in Fig. 2.

Supposing a transfer is about to be effected, the downward movement ofthe transferrer from the position shown in F 1 to that shown in Fig. 2operates to bring the stud 13 against the lower end of the slot 22, andthe toothed feedpawl clicks over one tooth of the ratchet as the pawl ispositively set or moved into operative position. This setting movementof the pawl, effected positively by or through the operative movement orstroke of the transferrer, serves to compress the actuating-spring, asshown in Fig. 2, wherein. the pawl is shown in position ready to effectthe advance of the hopper. The rise of the transferrer as it returns tonormal position permits the spring to act upon the feed-pawl to lift thelatter, and thereby tlu'ough its cooperation with the ratchet to advancethe hopper, and just before the transferrer has completed its upwardstroke the hopper will have been advanced the full predetermineddistance, so that the stud 13 is moved upward a short distance away fromthe bottom of the slot 22 as shown in Fig. 1, the spring effecting theadvance of the hopper in a yielding manner, as will be maniest, andpreventing shock or jar.

In order to prevent retrograde movement of the hopper under normalconditions, and also to prevent any reverse movement during the setting(of the feed-pawl, a detaining device or detent-pawl is provided tocooperate with the ratchet, said pawl 26 (separately shown in Fig. 7)having a ratchet-engaging tooth 27 and an adjacent rearwardly-extendedarm 28, provided with a hook 29 at its extremity, and the lower portionof the pawl eccentric to its hook 30 is enlarged, or widened, a s at 31,the hook being mounted. to rock on a fixed fulcrum-pin 32 on the hopperstand 3. The detent-pawl is thus located between the transferrer and theinnermost I dish 1 of the hopper, tooth 27 engaging the ratchet belowthe feed-pawl tooth 19'. When the hopper is advanced, the detent-pawlclicks over the ratchet, and its weight causes it to drop rearwardlyinto the next tooth and to prevent rotation of the hopper in a directionopposite to the arrow 100,- Fig. 1. A lateral lug or projection 33 isformed on the outer face of the detent-pawl for a purpose to bedescribed Referring to Fig. 2, it will be seen that the detent-pawlremains in operative engage ment with the ratchet during the settingmovement of the feed-pawl, so that at such time the hopper cannot bejarred or accidentally moved in a retrograde direction A secondlaterally-extended lug or projection 34 is formed on or secured to thedete'nt-pawl at its upper end substantially opposite to the tooth 27 andin such position relatively to the finger 17 that when the feed-pawl ismanually retracted the finger will engage the lug 34 and will retractthe detent-pawl from engagement with the ratchet, such manual retractionbeing effected by the operative grasping the finger-piece and swingingthe feed-pawl forward into the position shown in Fig. 3, thus clearingor freeing the hopper from the control of its feed mechanism and thedetent device. This will be referred to hereinafter. I have provided anovel and efiicient stop to prevent overrunning of the hopper when it isadvanced andto limit the advance movement to a predetermined amount. ITo this end I have provided a stop-pawl 35, (see Fig. 6,) having a tooth36 at its rear or free end provided with an upright face 37, adapted tocooperate with the leading face of one of the ratchet-teeth, and at itsouter end the stop-pawl is provided with a semihub 38, which looselyembraces the transferrer-hub 8. The stop-pawl is thus mounted to rockconcentrically with the axis of the transferrer, and it extendsrearwardly to the-ratchet, passing between the detentpawl 26 and thefeed-pawl. The hook 39 on the free end of the stop-pawl has attached toit one end of a spring 40 the other end of the spring being attached tothe hook 29 on the extension 28 of thedetent-pawl, the spring by itscontraction tending to swing upward the stop-pawl toward the detent-pawland retaining the tooth 36 of the stop-pawl in operative engagement witha ratchet-tooth under normal conditions. The stop-pawl is provided withcams 41and 42, and a lug'43, extended laterally from the inner face ofthe body 16 of the feed-pawl, is "arranged to co,- operate with one orthe other of the cams.

When the feed-pawl is set, the downward movement thereof causes thelug'43 to engage the cam 42 and depress or'swing downward the stop-pawl35 disengaging the tooth-face 37 thereof from the ratchet, as shown inFig. 2, so that the ratchet can advance on the feed movement of thefeed-pawl far enough to carry the last-engaged tooth beyond the face 37of the tooth of the stop-pawl. The advance of the hopper is initiatedbefore the spring 40 is free to lift the stop-pawl into the path of thenext tooth of the ratchet, the lug 43 cooperating with the cam 42 longenough to permit such initial movement of the hopper. As the advance ofthe latter is continued, however, the stop-pawl rises until it engagesthe fresh tooth of the ratchet, and when the stop-pawl and ratchet arein the relative position shown in Fig. 1 it will be seen that furtheradvance of the ratchet cannot be effected, for the push of the hopper istransmitted through the stop-pawl in a line which substantially passesthrough its axis. Hence the hopper is stopped after a predetermined Therise of the stop-pawl is of advance. course limited by the engagement ofthe point of the ratchet-tooth with the corner formed by intersection ofthe faces 37 and 44 of the stop-pawl. There is no direct connection orengagement at any time between the transferrer and the ratchet,the-hopper advance being efiected by or through the actuatingspring 25,and its stoppage when advanced by or through the cooperation of thestoppawl and ratchet, as explained, so that there is no hard bump on theendmost filling-carrier of the series when the latter is moved intotransferring position against the fixed stop 6. 'e v If theoperativedesires to free the hopper from its controlling means, hereinbeforedescribed, so that it can be turned freely in either direction, for thepurpose of inserting filling-carriers or for any other purpose needful,he grasps the finger-piece 20, pulls the feed-pawl forward, the latterswinging at such time on the pin 13 as a fulcrum, and the finger 17 bycooperation with the lug 34 of the detentpawl withdraws tooth 27 of thelatter from the ratchet as the manual retraction of the feed-pawlwithdraws its tooth 19 from engagement with the ratchet. As thefeed-pawl is thus retracted the lug 43 thereon is brought intoengagement with the cam 41 on the stop-pawl 35, and the latter isdepressed or swung downwardly about its fulcrum into the position shownin Fig. 3, withdrawing its tooth from engagement with the ratchet, sothat the hopper is freed entirely from engagement with all three pawlsand the operative can turn the hopper on its axis, as desired. Byrasping the hook 29 on the free end of the fetent-pawl and pulling thelatter forward the tooth 27 is withdrawn from the ratchet, and the lug34 on the detent-pawl en ages the adjacent edge of the part 18 of te/feed-p'awl and swings the latter forward, withdrawing its tooth 19fromthe ratchet, the feed-pawl then acting,

either one of the feed or detent members can be disengaged from theratchet by or through manual disengagement of the other member from saidratchet.

The lug 33 on the lower portion of the detent-pawl projects beneath thestop-pawl and limits its downward movement and at the same time acts inan indirect way to limit the manual retractive movement of the feed anddetent pawl. When the finger-piece is released, the feed-pawl returns tooperative position by expansion of the spring 25, and the detent andstop pawl are restored to position in which they can cooperate with theratchet, and if the hopper has not been left by the operative in suchposition that the teeth of the several pawls can immediately andproperly engage the ratchet a slight movement of the hopper will carrythe points of the ratchet-teeth forward far enough to permit theimmediate positioning of the several pawlteeth, restoring the parts tothe condition shown in Fig. 1. The detent-pawl cooperates with theratchet at a point intermediate the feed and stop pawls in theconstruction herein shown and described.

Changes ormodifications in the details of construction may be made bythose skilled in the art without departing from the spirit and scope ofmy invention, one practical em bodiment of which is herein shown anddescribed.
